A wood fire at center has red arrows labeled A pointing upward to a pair of hands. A red arrow labeled C points up and out toward a fire poker held by hands. The poker is grey except the tip, which is orange. Red arrows labeled B point outward to a pair of hands. In which scenario does radiation occur?

A
B
C

Its B for whoever needs it.

B

Explanation: there ya go shawtay :)

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
